Synchronizer having three pyramidal faces

Abstract

The invention is a 3D surface synchronizer, belonging to automobile driving device field, including: two-stage gear, inner conical ring, outer conical ring, medium ring, synchronizer spring, tooth case, gear hub, slide block, one-stage gear, first groove, slide block groove, and second groove, where inner conical ring, outer conical ring and medium ring are set in sequence from inside to outside to compose a friction ring on the gear, the inner conical ring is covered on the conical surface of the gear, the medium ring covered on the inner conical ring and the outer conical covered the medium ring, the medium ring is connected with the two-stage gear and one-stage gear by the grooves on the stage tooth, the slide groove is on the inner wall of the tooth case, the whole slide block is inserted in the groove of the gear hub, two synchronizer springs tightly adhere to two sides of the gear hub, respectively, and the outer conical ring is set with groove at the big end. It largely enhances synchronous torque, thus shortens synchronous time and widens the working range of the synchronizer, etc.

Description

technical field [0001] The invention relates to a synchronizer structure, in particular to a three-cone synchronizer for a manual transmission. The utility model belongs to the field of automobile transmission devices. Background technique [0002] In recent years, single-cone manual transmissions are mostly used in domestic and foreign automobile transmissions. This kind of transmission is more difficult when changing the first and second gears, the shifting is not smooth, and the driver's labor intensity is relatively high; in addition, some drivers do not grasp the timing of shifting gears properly, such as downgrading to the first or second gear when the vehicle speed is too high. At this time, the phenomenon of not being able to enter the file is particularly obvious. Transmission manufacturers have made efforts to improve quality, but with little success. In fact, the fundamental reason for the poor synchronization performance of the first and second gears is that t...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art that it is difficult to change the first and second gears, and the gear cannot be shifted, and to provide a three-cone synchronizer, which greatly enhances the synchronous torque, thereby shortening the synchronous time and widening the synchronous position. It can effectively improve the synchronization performance without changing the size of the original transmission, greatly reduce the shifting force, reduce the labor intensity of the driver, and improve the comfort of the vehicle
